  • the invention relates to an air conditioning system, in particular motor vehicle air conditioning, according to the preamble of claim 1.
  • an air conditioning system in particular motor vehicle air conditioning, provided, with one after a blower, one Evaporator, a heater and / or a heater in an air duct housing arranged mixing space, of which a plurality of air channels branches, which are controllable by means of flaps, wherein at least two adjacent air ducts are controlled by a common flap, and at least one flap is provided, wherein the pivoting path its blocking surface or its wing in an air duct or along the End of an air duct takes place without the blocking surface or the wing in protrudes the mixing room.
  • the flaps in the Mixing room protrudes, a possible noiseless air flow is possible.
  • the air distribution and the amount of air can be simpler and more precise to adjust.
  • the mixing chamber can be optimized more easily, so that a good mixture of the air before entering the air ducts takes place.
  • a flap is designed as a cylinder flap which laterally in Mixing space is stored, wherein it is in particular designed such that it has no protruding into the mixing chamber elements.
  • the side surfaces, which are radial or substantially radial, are in the next Proximity to the mixing chamber wall arranged so that they have no negative influences to have the air distribution.
  • the cylinder flap has at least one longitudinal direction at one end of the locking surface of the cylinder flap extending, approximately in Radial direction outwardly facing projection in at least an end position in abutment with a formed on the air guide housing Stop is.
  • protrusions are at both ends of the blocking surface provided, which in each end position with a corresponding get formed on the air guide housing stop.
  • At least one flap is preferably designed as a double-leaf flap, wherein the pivot axis in one end of a partition of two air ducts runs so that the air flows in the two air channels are not affected becomes.
  • the two wings of the flap are preferably at a fixed angle arranged to each other.
  • Such a double-leaf flap allows a easy control of two air channels, with the required effort can be kept within limits.
  • the two wings of the Double-leaf flap in an angle different from each other at 108 ° arranged. An angle between 90 ° and 130 ° is preferred.
  • the two wings are preferably formed asymmetrically, in particular they are different in length and / or have a different shape on, in particular, one or both wings are curved so that another flap, especially a cylinder flap in can pan the appropriate area.
  • At least one air channel can be closed by two flaps, see above that, for example, controlled with two flaps three air channels almost anywhere can be. In particular, intermediate positions of Flaps possible.
  • An automotive air conditioning system 1 has an air guide housing 2 a blower 3, an evaporator 4, a heater 5 and a heater 5a,
  • a PTC heater for air temperature control
  • a mixing flap 6 for air temperature control
  • a mixing chamber 7 to the mixture the cold and warm air
  • a defrost air duct 8 to defrost the Windshield
  • a ventilation air duct 9 for fresh or recirculation into the vehicle interior through the center or side jets
  • one Footwell air duct 10 for fresh air or air circulation in the footwell
  • two flaps 11 and 12 which control the air distribution on the serve three air channels 8, 9 and 10.
  • the flaps 6, 11 and 12 shown differently for clarity.
  • the mixing flap 6 is designed as a cylinder flap, the side in the mixing chamber 7 is mounted so that the pivot axis 6 'through the mixing chamber. 7 runs, wherein the blocking surface 6 "along the edge of the mixing chamber 7 pivotally is.
  • the blocking surface 6 is substantially cylindrical, where it corresponds to the lateral surface of a quarter of a cylinder.
  • the sides are provided with continuous 90 ° circle segments to which in the pivot axis 6 'pin (not shown) for storage and Drive the flap 6 are arranged.
  • the pins can also with provided a toothing or on the pin, a gear provided be.
  • the flap 6 For better sealing are on the flap 6 in the longitudinal direction of the blocking surface 6 "extending, radially outwardly extending projections provided in the end positions of the flap 6 provided on the housing 2 Abut attacks.
  • the flap 6 is in this case designed such that the mixing chamber 7 is substantially free of flaps, i. it runs in particular no shaft or stiffening in the pivot axis 6 ', which the would affect air flow.
  • a double-leaf flap flap 11 is provided wherein the pivot axis 11 'at the end of the intermediate wall between the two air channels 8 and 9 is arranged, so that the one wing 11 a the flap 11 pivots into the air duct 8 and the second wing 11 b the flap 11 in the air duct 9 pivots in, so they in no Position in the mixing chamber 7 protrude.
  • the two wings 11 a and 11 b of Flap 11 are arranged at a fixed angle to each other, wherein the Angle is slightly more than 90 °.
  • the first wing 11 a is present straight, the second wing 11 b formed bent, the curvature being approximately the curvature of the flap 12, which will be described in more detail below, corresponds or slightly smaller than the same, since the wing 11 b outside the Locking surface 12 "of the flap 12 is arranged.
  • One of the previously described mixing flap 6 corresponding cylinder flap forms the flap 12, said flap 12 only an angle of about 65 °.
  • the flap 12 is used to control the air supply in the ventilation air duct 9 and the footwell air duct 10, wherein they are stepless between their end positions by pivoting about their pivot axis 12 ' is adjustable. Also, this flap 12 protrudes, apart from the side surfaces, not in the mixing chamber 7.
  • the two flaps 11 and 12 can be adjusted as desired, not interfering with each other. Furthermore, the mixing room remains Flap-free, so that it is designed for optimal mixing can be.
  • Fig. 2 shows a second embodiment, in which the same or the same effect Elements are provided with reference numbers higher by 100 than in the case of first embodiment.
  • the arrangement or function of the blower 103, the evaporator 104, the heater 105, the auxiliary heater 105a, the Mixing valve 106, mixing chamber 107, defrost air duct 108, the Ventilation air duct 109, the footwell air duct 110 in the air duct housing 102 of the air conditioner 101 does not differ from that of the first one Embodiment, so that will not be discussed in detail.
  • the flap 111 is between the defroster air duct 108 and the vent air duct 109 again as Double-wing flap formed, wherein the pivot axis 111 'turn proceeds accordingly.
  • the wings 111 a and 111 b are at an angle of arranged about 110 ° to each other, wherein in the present case both wings 111 a and 111 b are formed straight, but the second wing 111 b is slightly longer as the first wing 111 a, as to be controlled by this wing 111 b Air duct 109 wider than the air to be controlled by the first wing 111 a 108 is.
  • a conventional flap 112 is provided, whichever after position (intermediate positions) something in the mixing chamber 107 protrudes, wherein the pivot axis 112 'in the intermediate region between the adjacent Air channels 109 and 110 is arranged.
  • the footwell air duct 110 formed such that the flap 112 only a relatively small Pivoting range has, so that the influence of the mixing chamber 107 low can be kept.
  • the footwell air duct end face with respect to a be arranged as a cylinder flap flap 12, wherein also a division of the footwell air duct on the two sides is possible, so the corresponding side surface (s) is the blocking function of the blocking surface 12 "in the corresponding position, in Fig. 1 is an opening the laterally arranged footwell air duct by a dotted line indicated. Due to the lateral arrangement of the footwell air duct results in the area shown on the right in Fig. 1 a gain in space.
